Abstract:

This paper studied the distribution characteristics of scattered light around peach pit using laser and computer vision technology combined with cutting step by step method similar to CT, and Matlab dealing with images to . The results showed that when incident light was stronger enough, the peach pit might affect the distribut of forward transmission light and backward scattering light. And the closer to the pit, the stronger the light was. After image treatment and data analysis, it was tentatively believed that fruit pit had played a role of weakening the strength of forward transmission light, i.e. the existence of fruit pit reduced the strength of transmission light signal. Light distribution of fruit internal tissues was affected by fruit pit. Within the tissues near peach pit, the gray curve no matter vertical or horizontal all accord with Gaussian distribution. Above results provided reference for realizing nondestructive detection of fruit internal quality by using laser image method from the optical point of view.
